Well, after getting my P3 pack from samsung i've noticed a few things wrong, all the files and stuff (for games, flash, manual, etc) are gone. That wasn't a big deal, but now in the systems sub menu, PC connection no longer shows. I've tried formatting, resetting default settings, and different firmwares but it doesn't show up. Any ideas?

Which different firmwares did you try? What firmware does your player currently use? What region is your firmware? Did you try to change regions? I think some regions don't support changing the connection type. Change to one of those and then change it back and see if that brings it back

The Korean region doesn't allow you to switch. Problem solved. If you want your Korean region, you'll have to get used to it. If you read the thread titles under P3 firmware, one of them explains how to change regions.

Firmware isn't region specific. I use 2.20 which was only released in Korea but my player region is Canada or USA (never looked) so I have both UMS and MTP but don't have Dictionary etc.

Just like pgh1969pa said, there is a thread on changing region. Not sure if it's stickied or part of the firmware thread, but I do recall reading it awhile back. The firmware doesn't have anything to do with your region settings. That's in a different file. Good luck.
